OK. I did some digging around on this. I'm a little bit out of my depth and completely out of time available but it seems the crawler code is missing the newest version of Joomla even though it is clearly in the returned XML from the repository.

It seems something changed a few weeks ago that broke some assumptions being made by the APS crawler.

The 3.0.5.2 Joomla is still offered because it is a newer, not older, version than the 2.5.11.5 found from the repository. My older server also offered both however when I try and create a 3.0.5.2 the next screen in the wizard refers to 2.5.11.5 again.

Flushing the APS cache directory and the database table and running the crawler again gives only 2.5.11.5.

Actually the latest version in the repository is 3.1.1-3 if only the APS crawler can be persuaded to see it.

Simon, out of curiosity I just put that patch on one of my dev boxes (Centos 6.4 x86_64 + apache), updated packagelist and about 45 newer packages have dropped in with a couple of new categories as well!

Thanks from me for looking at that - I look forward to seeing an update rolled into ispconfig.
